Atomization mechanism and powder morphology in laminar flow gas atomization

Hybrid Gas Atomization for Powder Production

Flow mechanisms in high pressure gas atomization

Very fine (d < 10/~m) metal and alloy powders can be produced efficiently by a high pressure gas atomization (HPGA) technique. Rapid solidification processing, metal injection molding, thermal spraying and other emerging powder-processing approaches benefit from the use of such fine powders. This paper reports on the results of an investigation of gas atomization process dynamics with emphasis ...

Atomization Uniformity in Gas -

There are two important aspects to good injector performance in rocket engines—the atomization performance (droplet size and distribution, for example) and uniformity of operation (even distribution of droplets in time and space). In general, both of these aspects are affected by the geometry and operating conditions of the injector. In studying atomization performance, prior work has largely f...

Atomization in Grammar Sharing

new insights with which to account for certain linguistic We describe a prototype SK~RED CmAt~eAR for the syntax of simple nominal expressions in Arabic, E~IL~lx, French, German, and Japanese implemented at MCC. In this Oamm~', a complex inheritance ian/cc of shared gr~mmAtlcal templates provides pans that each language can put together to form lansuug~specific gramm-ti~tl templates. We conclud...

Modeling of liquid metal flow and heat transfer in delivery tube during gas atomization

A numerical model is developed to describe the flow and heat transfer behavior of liquid metals in a cold delivery tube during gas atomization. Numerical calculations for liquid In, Sn, Bi, Pb, Zn and Sb are performed to investigate the influence of processing parameters and material properties on the flow and cooling of the liquid metals, and to predict the minimum melt superheat that is neces...
